GEORGE S. FAULKNER, OF STAFF CRDVILLE, CONNECTICUT.

Letters Patent No. 66,818, dated July 16, 1867.

IMPROVEMENT IN CAM FOB. LOOMS,

TO ALL WHOM IT MAY CONCERN:

Belt lrnown that I, GEORGE S. FAULKNER, of Staffordville, in the countyof Tolland, and State of Connectieut, have invented a new and improvedTreadle and Cam for Looms; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of'this specification, in which-Figure 1 represents a side elevation of my invention.

Figure 2 is a horizontal sectional view of the same, the plane ofsection being indicated by the line we, fig. 1.

Similar letters of reference indicate like parts.

This invention relates to a new device for operating the heddles on a10cm, and consists in a novel construction of the cam, by whieh'therequired motion is imparted to the treadle; also in the arrangement ofa. block, which is secured to the treadle, and which is worked by theflanges and side of the cam. The parts are so arranged that the heddlesare held in the required position while the shuttle is being thrown.

A represents an upright treadle, which is pivoted by a pin, a, to theframe of the loom, and which is connected by means of cords b .5 withone of the heddles. B is a horizontal shaft, which receives motion fromsuitable mechanism. C is the cam, which is mounted on the cylinder, andwhich consists of two segmental pieces, 6 and c. The former is an almostsemicircular disk, having a continuous flange, d, around its periphery,on its inside, (see fig. 2.) The portion 0 is an irregular. quadrant,having one straight side and one curved side, as is clearly shown infig. 1. A continuous flange, e, is arranged on the outside of theperiphery and curved side of this earn 0, and a flange,f, on thestraight, radiant side of the same, the latter flange not quite reachingto the periphery of the cam, as is clearly shown in fig. 1. D is aplate, which is secured to the outside of the treadle, and which has'apin,g, projecting from its extremity towards the in srde as shown in andby dotted lines in fig. 1. When the pin 9 is in the earn a so as to fitover the flange Eon the curved side of the same, as shown in fig. 1, andwhen then the shaft B is turned in the directionof the arrowIin fig. 1,the harness will be raised, and will be held raised while the pin 9 isheld on the periphery of the cam e, and until it slips off the cam 0through the opening between the flanges e andf. The lower edge of theearn 6 will then press upon the upper inclined surface of the block D,and will gradually lower the harness by forcing the whole length of lthe block (Z, between the flange d and shaft B, so that the end of theblock and the pin 5 rests against the shaft B. The harness is then down,and will be kept down until the cam 0 takes hold of the pin 9 again bymeans of its flange e, and brings the pin 9 to the periphery of the cam0, whereby the harness is raised. When the pin g rests against the shaft13 it is, as soon as the cam b has passed, brought between the end ofthe flange 6 on the curved side of the cam c and the shaft 13, and thecurved side of the cam a presses then upon the inclined upper side of atriangular projection, h, from the treadle, thereby gradually moving thetreadle 011' the shaft and raising the harness. Fig. 1 shows the curvedside of the earn 0 acting upon the triangle 7i, and moving the lower armof the trcadle in the direction of the arrow 2. For each heddle shouldbe arranged a treadle, A, and a cam, C.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The double-faced earn 0, when arranged on a shaft,13, and when provided with flanges d, e, andf, in combination with theinclined blocks D on the treadle, the latter being provided with a pin,g, as set forth.-

GEORGE S. FAULKNER.
